Infrared vs. Capacitive: Which touch technology is right for you?

Infrared vs. capacitive which touch technology is right for you?

From infrared to capacitive to the perfect touch and back again – the ideal solution is the technology that suits your area of application. This keeps workflows in balance, as practice shows today. There is no one-size-fits-all solution. It is therefore more helpful to recognise that the right technology is always the best. Touchscreens are everywhere today: in schools, offices, display systems and industrial applications. But not all touch technologies work the same way.

How the two technologies work

A hand touches the VS-S-C3 display—a red infrared grid visualizes precise touch detection in real time.

Infrared touch (IR)

With infrared technology, a frame with LEDs and sensors generates an invisible infrared light grid above the display. As soon as a finger, pen or other object interrupts the light grid, the system detects the touch and calculates the position precisely. The big advantage: the technology works with fingers, gloves, pens or any other object.

Capacitive touch (PCAP)

Capacitive technology works with a conductive layer in the display that registers changes in the electric field. A network of electrodes projects an electromagnetic field onto the screen surface. When the field is touched with a finger or a special stylus, the electrical capacity changes. This change is measured to determine the exact position. However, only conductive objects trigger the touch – but the technology is very precise and fast, ideal for multi-touch gestures.

Infrared touchscreens – the flexible ones

Advantages of infrared technology:

Flexible operation: Works reliably with gloves, fingers or any stylus
Fast response time: Smooth and precise input without significant delay
Multi-touch support: Multiple simultaneous touches possible
High image quality: No additional layer on the display, the image remains clear and sharp
Robust and durable: Resistant to scratches

Capacitive touchscreens – the precise ones

Advantages of PCAP technology:

Flat design: No annoying frame necessary
High robustness: Surface made of hardened safety glass, scratch-resistant and easy to clean
Precise writing feel: High writing accuracy and natural input
Gesture control: Supports drag & drop, zooming and rotating
Multi-touch capability: Multiple touch points simultaneously

Palm detection – write as if on paper

No false triggers: resting palms or hands are not recognised as touch points
Advantage for beginners: writing, calculating, drawing and using analogue blackboard tools feels just like using an analogue blackboard or paper

“The most perfect technology is the one that goes unnoticed.”
Richard von Weizsäcker

The decision is yours

Select capacitive if:

Precise writing and drawing are paramount
Gesture control is important
A flat, elegant design is desired
Work is mainly done with fingers or special pens

Select infrared if:

Flexibility in operation is required
Work is carried out with various objects
Maximum image quality without additional layers is required
Robustness in harsh environments is important

Both technologies have their merits – the choice depends on your specific area of application.
